IoT Tutorial
To build a Weather Detection System to get real-time weather metrics live onto mobile notifications
Problem Statement
SenseHat Board will
measure weather
metrics of Temperature,
Humidity & Pressure
onto Raspberry Pi
1
We will use Raspberry Pi
to transfer the weather
data and display the
results on the SenseHat
board
2
We will use Instapush
API and Python Script to
push these notifications
across the internet
